Deterioration Models for Life-Cycle Cost Analysis of Bridge Decks in Nebraska

Abstract: Deterioration models are vital to life-cycle cost assessments of bridges. Maintenance and user costs depend on bridge conditions, which vary across the period of analysis. The quality of LCC-based decisions depends on the accuracy and efficiency of the deterioration models used to predict the remaining service life of highway bridges. In Nebraska, the national average deterioration rates are used to predict the condition of bridge components. These rates do not represent the actual performance of bridges in Ne… Show more

“…This study uses NBI for developing regression models for bridge condition prediction. It should be noted that because the deck of bridge deteriorates more rapidly than the superstructure and substructure (Bolukbasi et al 2004;Hatami et al 2012), prediction models were developed only for bridge decks.…”

“…Predicting bridge condition with respect to its age using the NBI has been studied extensively in the past decade (Li et al 2010;Tabatabai et al 2010;Hatami et al 2012). However, because the NBI does not include any information about the applied load, deterministic approaches (e.g., finite element analysis) are preferred for quantifying the overweight load effects on bridges (Chotickai et al 2006;Dey et al 2014).…”
